El Gravetiense de Bolinkoba (Bizkaia) a la luz de las excavaciones antiguas y recientes

Abstract

The archaeological site of Bolinkoba is located in a small cavity in the mount Unzillatz (Abadiño, Bizkaia). José Miguel de Barandiaran and Telesforo Aranzadi excavated this cave between 1932 and 1933. Various circumstances, such as Spanish Civil War and the exile of Jose Miguel de Barandiaran, delayed the publication of the excavation report until 1950. The stratigraphic sequence includes different layers of the Upper Palaeolithic (Gravettian, Solutrean, lower magdalenian, Final Magdalenian, Azilian). Various aspects like the importance of Bolinkoba archaeological record, the absence of analytical not existing at the time of excavation (absolute Chronology, Sedimentology, Micromorphology, Paleobotany, etc.) or the long period of time that the cavity has been without a monitoring of its condition, has led us to initiate a research project (together with the Provincial Council of Bizkaia) since 2008. The aim is to get a proper perspective on stratigraphic evolution of the site, including results on the surrounding environment and the formation of the deposit. On the one hand, we are working with the material and information available from the excavation of the last century, and secondly, we focus our current performance in the preserved stratigraphic section and the possible presence of other areas with sediment in primary position.
